Fire Extinguished on Russian Nuclear Sub (VIDEO)

Russian firefighters have finally put out a huge fire that engulfed a docked nuclear submarine while crewmembers remain inside.

The submarine fire broke out on the Yekaterinburg  Thursday at an Arctic shipyard outside of the Russian city, Murmansk , where the sub was in dry-dock and sent 3o-foot flames into the air through the night. 

Seven crewmembers of the crew were hospitalized after carbon monoxide inhalation, and an unspecified number of crew remained in the submarine throughout the fire, though it is not clear whether the crew was trapped or ordered to stay inside. 

Firefighters battled the blaze for hours upon hours, spraying the sub’s rubber coated hull with water continually to cool off the smoldering submarine until it was finally extinguished. 

The Russian military has supposed that the fire was ignited on wooden scaffolding and then ravaged the sub’s outer hull.  Russian military prosecutors have launched a full-scale investigation to determine if safety breaches were to blame for the fire, and President Dmitry Medvedev instructed cabinet officials to enforce punishment on those who are responsible.

A defense ministry spokesman for Russia said in a statement that there was never any danger of the fire spreading inside of the sub and that the fire was completely external.  The statement also stressed there has been no radiation leaks or increase in radioactivity.

The Yekaterinburg is a 1985 Delta IV-class nuclear powered submarine that carries nuclear-tipped intercontinental ballistic missiles.
